In anticipation of the big day, the former girl next door posted a picture of her marriage license on Monday.

“We did it! Last wedding prep item taken off the checklist—we went and got our marriage license this morning,” she wrote.

The wedding is the next big step in Holly’s fairy tale romance; not only did the Insomniac Events CEO propose atop a Ferris wheel at the Electric Daisy Carnival, but she also had an Alice In Wonderland-themed engagement party last month.The couple welcomed their own little princess in March, named Rainbow Aurora. While her middle name may be reminiscent of a certain Disney princess, Holly told In Touch exclusively in March that her first name was actually inspired by a former classmate.

“I was always jealous of her name,” the newlywed told In Touch at the time. “If getting teased about her name is the worst thing that’s going to happen to her, bring it on!”

While there’s no official confirmation of who was included in the couple’s reported 150 guests, former housemate and Girls Next Door costar Bridget Marquardt has been sharing pictures of Disneyland via Twitter and Instagram.

This is the first marriage for both husband and wife, who have been together since late 2011.
